ELECTRIC IMARKING DEVICE.

Application filed December so, 1925. Serial No. 153,014.

This invention relates to an electric branda device that may be adiuiniageously used for branding. marking and otherwise identifying tires, shipping boxes, packages and various kinds o't merclmndise. llt may be used for branding live stock, but has been especially designed for addressing shipping bones. crates and the like so that there practically a permanent address that cannot become accidentally displaced during shipment or conveniently changed with fraudulent intent. As a tire marker our device will permit the owner of the tire placi. his name-and address thereon and thus minin'iize the nefarious practice of stealing tires or at least provide tire identificati on by which a stolen tire may be recovered.

Our invention further aims to provide an electric marking device with interchangeable type that may be easily and quickly set to provide desired indicia. The device is constructed so that the parts may be easily and quickly assembled, safely handled and conveniently used.

The co .struction entering into the marking device will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure 1 is a longitudinal sectional view of the device;

Fig. 2 is a bottom plan of the same, and

Fig. 3 is a cross sectional view of the device.

The device comprises a substantially cyl'lilQllCtl casinc 1 that may be made or metal or any suitable n'iaterial. The top of the casinp has a central interiorly screw threaded boss 2 for the stem 3 oi a handle by which the device may be conveniently manipulated.

The bottom of the casing has a longitudinal enlargei'ncnt 5 provided with a curved longitudinal slot (5 and the greater part of this slot is dove-tailed to form a tapering seat 7 or walls which taper inwardly towards the bottom of the enlargement 5. One end of the slot 6 is closed by an end wall 8 of the enlargement 5 and the opposite end of the slot is open so that tapered type 9 may be placed inthe slot 6 on the seat 7 with the taper of the type and seat preventing radial movement of the type. The type are preferably made of metal and any suitable font may be used which includes spacers or blanks 10. The selected type and spacers are placed in the open end of the slot 6 in their order, and shi't'ted lenghwise ot the slot until tilled, so that the t: ie may be held in place by an endwise clamping action that prevents longitudinal displacement of the type. In some instances the slot and type may be arcuatcd, as shown in Fig. 2 or any other configuration iim iarted to the sam while in other lUSi'llltCS a. single u'mrkin element mav be mounted in the enlargement 5. All of mean radius of an automobile tire, i. e., the

average ol? the external and internal radii. By diminisl ing the curved slot 6 accordingly, the device may effectively be used for marking automobile tires as indicated in the introduction to this description.

The ends of the casing 1 are interiorly screwlbreaded 11, and in one. end (it the screwed and hollow head 12 having av central opening for a lead-in conductor 13.

Screwed in the opposite end of the casing an end abutment 1 1 provided with a central stud or screw 15 on which is mounted a head 16 that engages the end of the casing 1 and the endmost type or blank in the slot 6. A wing nut 1? is mounted on the screw 15 to hold the head 16 in place so that it may coogerate with the end wall 8 of the slot 6 in holding the type and bla.ks assembled in the enlargement f.

Clamped between the abutment l t and the head 12 '5 an electric heating unit comprisular insulator 18 with a. terminal i g a. tub plate 19 samlwiched between the end oi" the lfififilillOl and f' 0 head 12. This terminal .ate is pro id i with binding posts 20 for the. wires 21 ot the conductor 13.

Suitably wouml about the insulator 18 is a heating element 22 and said insulator is apcrtured, as at 23, so that end convolutions ot' the wound element may e. tend into the insulator having connection with the binding posts 20.

The electrical heating; unit is in proximity to the inner ends of the type so that said type will be heated to the extent of making: a bu ned impression when the type are pla 1 against a piece oi wood or other material forming; the side wallv oi a shipi ing box, crate or the like. The handle 1 will permit oil pressure eing brought to bear. it necessary and obviously this handle may be shaped so that both ends may be employed to produce a uniform pressure throughout the length of the marking instrumentality.

Our device, as herein shown and described, is suggestive of other structures, for in. a casing of greater length so as to pi I a compartment between the head 16 and the abutment 14 for type not being used. Again, the casing 1 may be made comparatively flat so as to accommodate a compitllttiWJLY fiat electric heating element that may be of the bar or ribbon type. In all instances We prefer to make the heatin unit detachable by clamping it within the casing and removing it endwise therefrom. The same is true regarding the type and since the insulation material is commonly used in connection with electrical devices, we intend to freely use the same wherever necessary to insure safety or conservation of heat.

One embodiment of our invention has been illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

hat we claim is 1. A marking instrumentality comprising a casing ha ing a curved longitudinal slot in its outer \r all adapted to receive type, said slot having a. radius of our *ature SubStdl'b tially equal to the mean radius of an automobile tire, whereby the device is adapted for marking such tires.

2. A marking inscrumentality comprising in combination a casing, a. hollow head fitted in one end of said casing, a flanged abutment in the other end of said casing, a heating element contra ly held. by said flanged abutment against said hollow head, a terminal plate sandwiched between said hollow head and heating element, connecting means on said terminal plate, a lean-in through said hollow head and connected to said terminal plate, said connecting means and lead-in being received in said hollow head.

In testimony whereof we afiix our signatures.
